Empty Tank Warning
Profile
When the spray tank is empty, there will be a prompt in the app and the aircraft will move
depending on the operation mode - ascend 3 meters and hover (Smart Operation Mode or F-
mode) or hover in place (Manual Operation Mode or Manual Plus Operation Mode).
How to Use
1. Press the Spray Button on the remote controller to turn off the sprinklers when the empty tank
warning is triggered in Manual Operation Mode. Failure to do so may cause the idling of the pump
of the motor and subsequently damage the parts. The sprinklers will automatically turn off in F-
mode, Smart Operation Mode or Manual Plus Operation Mode when there is only 300ml liquid
left in the spray tank.
2. Ensure the aircraft is in Manual Operation Mode, and then land the aircraft and stop the motors.
Refill the liquid tank and tighten the lid.
3. Press the Spray Button on the remote controller to discharge the remaining air in the pump
until the empty tank warning in the app disappears. Press the Spray Button again to stop
discharging.
4. Ensure the aircraft is in Manual Operation Mode, and then take off.
5. Elevate the aircraft to a desired altitude in F-mode, Smart Operation Mode or Manual Plus
Operation Mode. Adjust the spraying distance between the aircraft and the vegetation to be within
the working range (1.5 - 4.5 m). Refer to the Terrain Follow System for details. Then toggle the
Operation Mode Switch or Flight Mode Switch to enter the desired mode.
